“Assisted Analysis”, the new function which has been implemented in ChessBase 14, offers to the user who is either entering moves or playing through a game valuable hints as to the tactical consequences of any possible move. This is achieved by means of coloured highlighting on the chessboard.
The fundamental idea behind this feature is based on the fact that modern chess engines working on high performing hardware can come up with the best move in fractions of a second. Unlike in the classical version of engine analysis in which the evaluation of a move is displayed in the engine window, the users do in fact get hints as to the quality of any specific continuation but in the long run when it comes to the reason behind the evaluation they are obliged to work it out for themselves. This way of working is significantly better at helping them develop their own tactical abilities and this circumstance is what makes the function so valuable in chess training.
Take care that Assisted Analysis is activated in the board window under Analysis!
Let us take a look at the function with some examples taken from games.
Lasker – Bauer Amsterdam 1889
After very passive play by Black in the opening the white pieces are poised to attack. Lasker now begins his decisive assault. How might the attack be continued?
A click on the white bishop on d3 produces a display of all the possible squares to which the selected piece could go highlighted with colour. The coloured markings reflect the evaluations made by the chess engine which is working in the background. In this case their interpretation is easy. Most destination squares for the Bd3 are marked in red and that colour designates a very bad move. In this example, quite specifically material is lost without any compensation. On the other hand, target squares which are marked in green promise success and hint at a good move. So in this case Assisted Analysis is pleading in favour of the bishop sacrifice on h7, the move which was chosen by Lasker in the game.
Which specific coloured markings does the function offer?
Bogoljubov – Alekhine Hastings 1922
White’s position looks terrible: he is a pawn down and his pieces have hardly any breathing space. A click on the black Nb4 and Assisted Analysis displays the evaluation of all possible destination squares according to the criteria described above. The move chosen in the game by Alekhine, to d3, finds favour in the eyes of the program and the square is outlined in green as being the best continuation.
In many positions you would like to know what then actually happens when you move a piece to a specific square which has been highlighted as critical (red) by the analysis function. Here too Assisted Analysis comes to the aid of the user with some really smart support. It is possible to have it show you the counter-move immediately!
In our example the d5-square is marked as critical. That is clearly because the piece can be taken immediately. But in many tactically more complex positions that is not always the case. Let us take a look at how we can display the counter-move by means of the analysis function.
Place the piece on d5, the square which is highlighted in red as critical, and then press the right mouse button, without letting go of the piece.
So the program then immediately shows the absolutely best counter-move!
Further important help for the user is the display of the evaluation of the position underneath the notation window. This display is always available in conjunction with the analysis.
Moreover this is also true for the option described above, having the expected counter-move displayed by a right click on the mouse!
When playing through a game, how can one have the function display the best move in any position, that is to say more or less ask for a tip? Of course it is possible to click on each piece and then look at the evaluations with Assisted Analysis. But there is an even more elegant method. It is simply possible to find out which piece can make the best move in the relevant position by scrolling the mouse wheel.
For our final example let us take a look at the following position:
Karjakin – Carlsen New York 2016
This position comes from the tiebreak between GM Carlsen (White) and GM Karjakin (Black) and finally decided the match for the WCh. Clicking on the white queen here displays the possible squares for the queen marked with various colours. In this position Assisted Analysis highlights only one move in dark green, whereas the remaining possible squares are outlines with a dark reddish-brown colour. The dark green displays a forced mate, the reddish-brown around the other squares shows that after one of these moves White will be mated. Here too, a right click on the mouse enables us to convince ourselves of this fact by seeing the counter-move.
Assisted Analysis also offers the following advantages:
• You can recognise right off how good any move is.
• As you enter moves you can concentrate completely on the chess board without constantly diverting your attention to what is being displayed in the evaluation window by a running chess engine.
• The function encourages the calculation of variations and in doing so the chess-playing abilities of the user are promoted/trained.
Tip: Assisted Analysis is not compatible with one-click entry. Whenever the function is activated, it is frequent that the most probable move is not played. The reason for that is that Assisted Analysis leads to the user clicking on several pieces in succession in order to check out how good each of them is. In order to avoid these conflicts a new input method has been implemented which is intended solely for rapid entry of games.
